Advanced Diagnostic Technology

Vonnahme Eye Care is proud to offer the latest in diagnostic technology to our patients. New advances in eye care allow us to take better care of our patients by providing earlier detection of disease and to better pinpoint causes to improve outcomes. 

Corneal Topography

Corneal topography provides the most detailed information about the curvature of the cornea. Using a very sophisticated computer and software, thousands of measurements are taken and analyzed in just seconds.

The computer generates a color map from the data. This information is useful to evaluate and correct astigmatism, monitor corneal disease, and detect irregularities in the corneal shape. The map is interpreted much like other topography maps. The cool shades of blue and green represent flatter areas of the cornea, while the warmer shades of orange and red and represent steeper areas.

This corneal map allows the physician to formulate a "3-D" perspective of the cornea's shape. Measuring astigmatism is important for planning refractive surgery, fitting contact lenses, and calculating intraocular lens power.

Topcon Maestro Robotic OCT

Ocular Coherence Tomography, or OCT, is an advanced eye scan suitable for patients of all ages. Similar to ultrasound, OCT uses light waves rather than sound waves to see beneath the surface of the eye. It allows your doctor to see the different layers which make up the back of the eye. 

Using this technology, your doctor can simultaneously take a digital photograph and a 3D cross section scan of the back of the eye. This allows us to instantly diagnose a number of common conditions. The scan is non-invasive, painless and can be completed in 60 seconds or less. 

Common conditions identified through regular OCT screening include: macular degeneration, diabetes, glaucoma, macular holes, vitreous detachments.   



QuantifEYE is a new technology that measures the relative health of your macula. We can now better determine your risk for Age Related Macular Degeneration (AMD) simply by determining other risk factors and getting your MPOD measurement. 

The test using the QuantifEYE device is simple, quick, non-invasive, and does not require dilation prior to examination. A base-line measurement is taken, and the results are your MPOD score. If you happen to test low (low MPOD scores=increased risk for AMD) to medium, your Eye Care professional may recommend supplementation to restore depleted levels of zeaxanthin and lutein in your macula. (With MPOD testing and supplemental intervention, it is possible to increase the pigment levels in your macula, thus lowering your risk for vision loss.) Your Eye Care Professional will then be able to determine through follow up screenings if nutritional intervention is resulting in increased macular pigment. 

Ask for this important test today. It's not too early to take steps to preserve your vision and restore your eyes to a healthier state. 


Dry Eye Analysis - Meibography

Meibomian gland dysfunction (MGD) is a common eye condition, yet many people don't realize they have it. You get it when there's a problem with a few dozen tiny glands in your eyelids that help make the oil layer of your tears.

Meibomian glands are the oil glands that line the edge of your eyelids, near your eyelashes. Around 25 to 40 meibomian glands line the upper eyelid and 20 to 30 line the lower eyelid. These glands secrete the oil that coats the eyes and tear film, to prevent the tears from evaporating too quickly.

Meibography is the process of measuring the quantity and quality of your existing meibomian glands using special technology. Your doctor will use this information to develop a treatment plan that's right for you. 


RightEye Functional Vision Testing

We are proud to offer a more comprehensive vision exam using advanced, state-of-the-art eye-tracking technology. The RightEye system enables our doctors to pinpoint functional vision and brain health issues, identify the root cause of reading problems, and improve athletic performance. In just 5 minutes, this proven, patented technology measures visual skills in ways that a standard eye exam cannot — enabling us to diagnose and treat underlying vision issues that affect our patients’ quality of life.

Functional Vision Testing - Your two eyes and brain must all work together to navigate the world. It’s this connection that makes up your functional vision. A standard eye exam, however, only checks your eyes’ physical health and ability to focus on stationary objects — it doesn’t measure critical dynamic vision skills such as eye movement and coordination.
